Would you uproot your life, leaving behind your family, your job etc if you dont like the weather in a country.
(Obviously theres always more than one advantage of moving someplace but to build a life somewhere, would weather be top 3 factors in choosing where to live).
If you feel that the weather is affecting your day-to-day life for the worse, absolutely. You are not obligated to stay for family or for a job. Prioritise your health, you can always visit relatives.
